dog. Fig- 27 is a detail showing the knotter in operation.

In the drawings all like parts are referred to by the same numerals, ofwhich 1 is the binding table or deck, on which th grain is deliveredfrom the harvester in the usual manner.

2, Fig. 9. is the oscillating binding-arm.

3 is the binder-arm shaft.

4-is an ear formed on the hub of the bindershaft.

5 is an arm hinged at one end to the ear 4 the compressor 6.

7 is a link pivotally secured at one end to the arm 5 and at the otherend to the free end of the crank-arm 8 on compressor-shaft 9, which isjournaledin suitable bearings below the binding-platform, and hassecured to its free end the crank 10, as shown in Figs. 3 and 4, andthis crank has an arm or stop 90, which normally rests against theframe, as shown in Fig. 3.

11 is a connecting-rod pivotally secured at one end to the crank 10 andat the other end to the compressing-lever 12, which is fulcrumed at 13to the frame, and is provided with a toe at its free end, and haspivotally secured at 1-1 the tension-rod 15, upon which is sleeved thecompressor-spring 16, adjustably secured thereto by suitable nuts andwashers 17.

18 is another lever fulcrumed on the same fulcrum 13 with thecompressing-lever, but adapted to move independently thereof. This leverhas three arms. The arm 19 bears a roller 20. The arm 21 terminatesin aneye 22, through which the tension rod 15 passes loosely and which servesas an abutment for the compressor-spring 16. Between the arms 19 and 21is placed the curved guide-bar 23, on which there is a projecting top24:, Fig. 21, against which the toe 35 is adapted to bear.

and having secured to it near the other end 25 is the third arm of thislever, and this has formed in its free end the eye 26, the rest 27, theabutment 28, and the stop 29.

30 is a movable stop pivotally secured to the eye 26 on the lever 18,and this stop carries at one end the roller 31, and to its heel it hashinged the tension-rod 32, which has sleeved upon it the spring 31, andprojects through the abutment 28.

36 is a U-shaped frame rigidly secured to the binder-frame and for thepurpose of supporting the knotter mechanism, as in the ordinaryconstruction of binder. The overhanging arm of the U-shaped frame ishollow and supports in suitable bearings therein the operating-shaft 37of the knotter mechanism. To the inner free end-of this shaft is securedthe cam-wheel 60, and to its outer free end is secured thesprocket-wheel 38, which latter is provided with the cam 39, against theface of which the rollers 31 and 20, heretofore described, bear.

40 is a sprocket-chain which passes around the sprocket-wheel 3S andaround the little idler-sprocket 41, carried upon the arm 42, which ishinged upon the end of the packershaft 91, and is adjustably secured bythe nut- 43 to the slotted guide-bracket 44. The lower portion of thissprocket-chain is guided on the under side of the curved guide-flange45, which is formed 011 the arm 42, and the upper portion of thesprocket-chain passes around the under side of the sprocket-wheel 46,which is loosely sleeved upon the packer-shaft 91. This sprocket-pinion46 forms part-of a clutch shown in Figs. 24, 25, and 26, of which thedriving-head 47, forming one part, is fast on the packer-shaft, andcarries two pins 48, either one of which is adapted to normally engagewith the arm 49 of the dog 50, which latter is pivotally secured to thepin 51 ot the loose sprocket-pinion 46. This dog has an arm 52, whichnormally rides on the hub of the sprocketpi11ion, and also an arm 53,which projects outwardly and is adapted to strike in the operation ofthe machine the trippingarm 54 when the latter is in the position shownin Fig. 3, and thereby trip the clutchdog out of gear. This tripping-arm54 is sleeved upon the binder-arm shatt3 (see Fig. 5) near the free endthereof, in proximity to the crank 55, so as to rest with its projectingflange 56 upon said crank, which is fast upon the binder-shaft. Thetripping-arm has a yielding connection with the crank by means of thespring 57, and a connecting-rod 92, Fig. 3, pivotally connects it withthe crank 93 of the tripping-shaft 04, which latter is secured insuitable bearings upon the binderplatform and carries the yielding arm95, which is adjusted above the binding-platform in an inclinedposition, so as to be lifted up on its free end when the bundle hasattained the proper size. The freeend of the crank 55 has hinged to itone end of the connectingrod 58, the other end of which engages with thewrist-pin 50 on the sprocket-wheel 38.

The knotter-operating cam-wheel 60 has formed around its periphery theannular delay-flange 64, and this is cutaway at three points, marked 61,62, 63, in Fig. 10. The cut-away portions 61 and 62 are formed bycutting the delay-flange away upon the outer periphery, and the cut-awayportion 63 is formed by cutting away the inner periphery of thedelay-flange. An oblique cam 61 is placed on the outer periphery of thedelay flange between the cut-away portions 61 and 62, and cogs 68 areplaced upon the side of the cam-disk in proximity to and in relationwith the cut-away portion 63 of the delayflange, and the cut-away end 65of the delayflange is formed on an incline.

66 is a cam-groove formed in the body of the disk, and this cam-grooveis partly concentric.

67 is a roller secured upon a wrist-pin on the wedge-shaped body formedbetween the eccentric portions of the cam-groove.

69 are ejector-arms carried by the shaft 37.

The knotter consists of the frame 70, which is provided with the hub 71,by means of which it is sleeved upon the shaft 37, and upon this hub isformed a gear-tooth 72.

'73 is the knottcr-shaft, upon which is se cured the knotter-pinion 74and the head 75.

This knotter is of the usual bill shape and has a movable jaw 76, whichmoves parallel with the fixed jaw 77, formed integrally with theknotter-head. The knotter-shaft 73 is hollow, and through it passes astem 06, to one end of which is secured the movable jaw '76 ot' theknotter-bill, and to the other end of which is secured an anti-frictionroller 78, which bears on the cam 70, formed on the knotter-frame.

S0 is a spring pressure-foot bearing against the free end of the stemwith the tension of the spring 81.

82 and 83 are contiguous flatdelaydiaces formed partly on the frame ofthe knotter and partly on the knotter-pinion, as shown.

84 is a support or bracket for supporting some of the operating parts ofthe knotter mechanism. This bracket is shown in Figs. 5 and 16. It hastwo ears S5 86, by means of which it is sleeved upon the hub 71 of theknotter-frame, and two legs 87 88, by means of which it is secured tothe breast-plate S9, and thereby forms a rigid support. The lower end ofthe leg 87 of this bracket has integrally formed with it the stationarytwinerest 97 and the twine-guide 100, Figs. 6 and 7, which by itsroundingconfiguration guides the twine from the straight portion 101oE-the needle-arm slot of the breast-plate into the lower curved end 102thereof.

1033 is a short shaft journaled in suitable bearings formed in thesupport 84, and this shaft is provided upon its inner free end with theshort crank 104, which carries the roller 105, which engages into thecam-groove 66 of the cam-wheel 60. Upon the shaft 103 is supported, asshown in Figs. 17 and 18, a hollow sleeve made in two parts 106 and 107,the

former being fast and the latter being loose upon said shaft, and themeeting edges of these two parts have projecting lugs or teeth in themanner of clutches to engage with each other, but allowing alimited-loose play to the part 107, and a coiled spring 108 sleeved uponthem with one end made fast to one part and the other made fast to theother part. The loose part 107 is provided with a crank 10.), to whichis pivotally selIO cured the rod 110, Figs. 5, 6, and 7, the other endof which is pivotally secured to the heel of the tucker 111. This tuckeris fulcrumed on a pin 112 between the breast-plate and the foot 87 ofthe support 84, .as shown in Fig. 5, and has a free play forward fromits normal position, (shown in Figs. 5, 6, and 7,) whereit rests againstthe stop 113.

From the shaft 103 is suspended the oscillating cord-holderframe (showndetached in Figs. 13, 14, and 15) by means of the hangers 114 and 115,which have eyes 116 and 117 formed on their upper ends, through whichthe shaft 103 loosely passes. The hangers carry the annular groovedframe 118. in which is removably secured the rotary ring 119, providedupon its inner edge with a series of notches 120 and upon the upper sidewith a series of lugs 121. A shoe 122 embraces the inner edge of therotary ring 119 by means of the groove 123 out therein, and this issecured to an arm 124, pivotally secured at 125 to the cordholder frameand provided with the spring 126, Fig. 14, the tension of which keepsthe shoe in its engagement with the edge of the ring. The cord-holder isfurther provided with a knife 127, (shown in Fig. 15,) attached to theend of an arm 128, which is pivotally secured at 129 to the under sideof the cordholder frame and carries the roller 130, which is struckperiodically by the portion of the cam-wheel to force its cutting-edgeagainst the cord to sever the same. The tension of the spring 131 tendsto keep said arm in its normal position. The flange on the camwheelengages between the lugs on the rotary ring and locks the same until thecut-away portion of the wheel arrives at this point,

when the riugis unlocked. The inclined por-' tion 61 is then broughtinto contact with the lugs and forces the ring one step forward. Therotary ring 119 is prevented from turning backward by means of alocking-pawl 132, Fig. 15, which is adapted to engage with the lugs 121,thereby preventing any sudden jar from altering the position of thering. The cord-holder is free to have an oscillating movement on theshaft 103, from which it is suspended, and this movement is broughtabout by means of a roller 133, carried by an adjustable extension 134of the arm 115 and engaging into the cam-groove 66 of the camwheel.

To the support or bracket 84, before described, is pivotally secured abell-crank 137, one arm of which carries a roller 135, Fig. 6, and a lug136, the former of which engages into the cam-groove of the cam-wheel,while the latter is adapted to be engaged by the roller 67, carried bythe cam wheel. The other arm of the bell-crank 137 has a notch 138, intowhich the cog-tooth 72 on the knotter-frame engages.

. In practice, the parts being constructed and arranged as described, itwill be seen that the operation of the binding mechanism is derived fromthe packer-shaft 91, which, as in the usual practice, is provided withcontinu ous motion derived from the operating mechanism of the harvesterin any suitable manneras, for instance, shown in the diagram Fig. 1,Where a sprocket-pinion 139 is secured upon the rear end of thepacker-shaftand around which the sprocket-chain 140 passes, whichconveys the motion from the operating parts of the harvester. The grainbeing delivered upon the binding-platform by the usual elevatingdevices, itis collected by the packers (which are of known constructionand operation) against the compressor-arm. As the bundle is forming, thefree end of the yielding arm 95 is gradually lifted up by the increasinggavel until by means of the connections described (which are adjustablefor the purpose of regulating the size of the brim dle) the trip-arm 54is lifted up sufficiently to release it from its engagement with the arm53 of the dog of the trip-clutch. This movement throws the trip-clutchinto gear and motion will be imparted immediately to the sprocket-chain40 by means of the sprocketwheel 46. The sprocket-chain imparts motionto the sprocket-wheel 38, which thereupon begins to revolve the shaft37, upon which it is fast, and also to convey the motion to thebinder-arm shaft by means of the connectingrod 58 and crank 55. Thesprocketwheel 38 makes one complete revolution, and this motion producesthe necessary oscillation of the binder-shaft to carry the binder-armsufficiently forward to lay the twine into the cord-holder and then backagain to its normal position. This rearward oscillation carries thetripping-arm 54 back to its normal position, where it will trip theclutch again and arrest the further movement of the binder mechanism.The movement of the binder-arm also actuates the compressor-arm tocompress the bundles,the normal position of the compressorarm beingshown indotted lines in Fig. 9, while the full lines show the positionit assumes while the binder-arm has finished its forward movement. Inthis position it is acted on by the tension of the compressor-spring 16,which is held between the two abutments 17 and 22. This abutment 22 ismaintained by the lever 18, which, as described, carries the roller 20,and as long as this roller travels on the circular portion of the cam 39(which it does until the bundle is tied) this, abutment remainsstationary. The abutment 17 yields, however, and by means of theconnection described the compressor-arm is permitted to yield to theforce of compression on the bundle, and the abutment 17 will approachthe abutment 22 untilthe pressure of the bundle is equal to the tensionof the compressionspring. Thus by adjusting the abutment 17 the amountof yield of the compressor-arm under the force of compression on thebundle, as produced by the relative opposite movements of the binder-arm and compressor, may be adjusted to any desired degree. In Fig. 4the action of the compression on the compression-spring is illustratedby a diiferent position of the toe 35 from the normal position in Fig.As long as the roller 20 travels on the circular portion of the cam 39,the compression is maintained; but at the time the tying of the bundleis completed the roller 20 arrives at the end of the circular portion ofthe cam and is free to oscillate sufficiently to permit thecompressor-arm to move out of the way below the binder-platform topermit the ejector to throw the bundle off. This withdrawal of thecompressor-arm is brought about by the action of the movable stop 30,the spring 3% of which is under tension, owing to its roller 31 beingforced to ride on the circular portion of the cam. (See Fig.4.) Thistension causes the lever 18 to oscillate as soon as it is free to do so,and thereby to carry by means of the dilferent connections thecompressor-arm out of the way until the roller 20 is again carried on tothe circular portion of the cam 29 and the parts restored to theirnormal position, while the roller 31 of the movable stop drops onto theradial por-.

tion 1&0 ot the cam-guide, and thereby forms a stop, which prevents aretrograde movement of the parts and takes up the slack in the clutch.

The operation of .the knotter mechanism begins with the movement of thetucker, which is actuated by the roller 105, which is the first one toenter the eccentric portion of the groove in the cam-wheel 60. Thismovement causes the tucker to oscillate on its pivot, so as to cause itshook-shaped free end to engage upon the twine, tuck it into thetwine-rest 97, so that it will be in proper position for theknotter-head to seize it. As shown in Fig. 9, the binder-arm preventsthe tucker from withdrawing to its normal position before the binder-armitself withdraws, and to permit the tucker to delay its reverse movementto the normal position I have constructed the yielding connection shownin Figs. 17, 18, and 19, which permits the roller 105 to return to itsnormal position under the action of the camgroove 66, while the tuckerretreats to its normal position by the tension of the spring 108, assoon as the tucker is free to retire, when the binder-arm gets out ofthe way. The twine is carried by the head of the binderarm through theannular cord-holder, which has one of its notches 120 in proper positionto receive the twine. The cam-wheel 60, engaging with its peripheralflange between two adjoining lugs on the rotary annular ring, keeps thesame locked until the movement of said cam-wheel brings the cut-awayportion between the two lugs, unlocks the ring, and permits the incline61' to engage the next lug and to turn the ring one step, thelockingpawl arresting it in such position. By this movement the twinedelivered by the binderarm into one of the notches is carried therebyuntil it is nipped by the shoe. Nowthe knotter begins to operate in theusual manner by the engagement of the cogs 68 on the cam-disk with theknotter-pinion 74, which is now free to revolve on account of thedelayflange Get being cut away at 63. To provide the necessary slack inthe twine for the formation of the loop, the cord-holder is nowoscillated toward the knotter-head by means of the roller 133, which nowenters the eccentric portion of the cam-groove in the cam-wheel. Thesecond cut-away portion 62 on the peripheral flange of the cam-wheel ismade to permit the knife 127 to keep out of the way of the twine untilits roller 130 is struck by the corner 65 on the cam-wheel, whichoscillates it sufficiently to cut the twine. The angular position of thetwine as held by the cordholder helps to guide the twine into the jaw oftheknotter, and the cord-holder is at itsnearest approach to theknotter-head at the time it delivers the twine into the jaw of the same.After the twine is cut the twine-holder is moved back to its normalposition. The knotter-head makes two revolutions. At the first it formsthe knot upon its head, and during its second revolution it strips theknot. This is accomplished by the roller 67 on the cam-wheel strikingthe lug 136 on the bellcrank 137', thereby causing the knotter-frame tooscillate and free itself from the knot. This movement is accomplishedmuch quicker by means of the parts described than it would beaccomplished by the roller 135 in following the eccentric portion of thecamgroove, which movement would be too slow on account of the revolvingmotion of the knotter-head, which demands a quick movement just at thetime when the jaws of the knotter-head are turned toward the bundle.However, the roller 135 returns the knotter again to its normalposition. To permit the roller 67 on the cam-wheel to elfect theoscillation of the knotter-head, the cam-groove is partly cut away topermit the roller 135 to get temporarily outside the cam-groove.
